Hi! It works without fostex FT17H? There is no need sound-proofing? Some measurements are? I have a pair of fe166en, I want to build somethings with them. Victor is too big. This is very similar what I have now, a Buschhorn MKII. It's better to have the throat to the front? Thank you for the answers!

Yes, I also think it's smarter.
Took me several drawings to reach my target.
By placing just ONE panel different I succeded getting a hybrid horn that was without parallel pieces.
The other differences are a result of HornResp and AJ-horn.

No, I don't have any measurements ; but I own , about 14 , different sets of loudspeakers to compare to.
This design is one of my best!!

I used the same cd's to voice them as for my "Eidoclone's" ; the midi concerti's hold up very wel!!

the tweeter is in series with a C ; 0,82 -2,2 uF and then parallel to the Fr.
add an R ; 1 - 2.2 ohms in series to the C to adjust the level of highs ; is room dependent.
At this moment , after burn-in , everyone uses only 2,2 uF.
